The Impact of Spatial Correlation on the Statistical Properties of the Capacity of Nakagami-M Channels With MRC and EGC

In this paper, the authors have studied the statistical properties of the instantaneous channel capacity of spatially correlated Nakagami-m channels for two different diversity combining methods, namely Maximal Ratio Combining (MRC) and Equal Gain Combining (EGC). Specifically, using the statistical properties of the instantaneous signal-to-noise ratio, they have derived the analytical expressions for the Probability Density Function (PDF), Cumulative Distribution Function (CDF), Level-Crossing Rate (LCR), and Average Duration of Fades (ADF) of the instantaneous channel capacity. The obtained results are studied for different values of the number of diversity branches and for different values of the receiver antennas separation controlling the spatial correlation in the diversity branches.
